YARN-BEAM.

have invented certain new and useful Improvements in Yarn-Beams, ofwhich the following is a specification. I

Our invention relates to an improvement in yarn beams; and particularlyto beams of the perforated cylinder type which are emyarn during dyeing,cleaning and other operations.

" The primary object thereof is to provide a yarn beam of durable andlight construction which is both convenient and inex-l pensive to makeand capable of being easily repaired in the case of damage or breakage.

A further object of our inventionls to provide a yarn beam .that isconstitutedof detachable and interchangeable parts which can be readilyassembled or dismounted; so that in case any of the elements become wornout or broken the same can be readily replaced and the beam thus put incondition for further use.

-The above objects and advantages of our invention will appear from thefollowing 1. description, taken in connection with the accompanyingdrawings, in which:

Figure 1 is a longitudinal section of our improved yarn beam; and Fig. 2is an end elevation of the same.

In the particular description of our invention we employ the numerals 1and 2 to indicate the heads or ends of our yarn beam, and it will beseen by reference to Fig. 1 that each of these heads has an annulargroove 3' formed in one face, into which are insertedth'e ends of theperforated body or cylinder 4 of the beam. This cylinder 4 and the heads1 andl2 are held in fixed relation when the parts are assembled to formthe .beam, by means of tie rods 5"; which run lengthwise ,of thebeam andare located inside the cylinder 4. through the heads 1 and 2, and aremade fast at their outer ends, so that the heads 1 and 2 and thecylinder 4 can be securely locked together. The grooves'3 will 7 ofcourse be of such width as to enable the cylinder 4 to fit snugly intothe heads 1 and 2 and make a very compact and rigid struc-.

enough for the purpose which the beam is designed to serve, stood. Theouter face of the cylinder will be lined with a non-corrosive metal,such as lead, indicated at 6; and this lead lining will also extend overthose portions of the faces of the heads 1 and 2 in which'the grooves 3are formed which are between the grooves and the peripheral edges of theas w1ll be readily under:

heads. By reason of this construction the cylinder 4 acts as afoundation body for supporting and reinforcing the softer yarn bearingsurface of non-corrosive metal designated at 6. Of course theperforations in the cylinder 4 will extend through the lead lining orithe" cylinder also; and it will now be seen that when yarn is wrappedaround the beam on the outer face of the cylinder 4 and between theheads, every' part of the beam with which the yarn may come in contactwill be properly lined, and even should certain parts of the beam becomecorroded by the action of chemicals when in use, the corrosion will notinjure the yarn because none of the corroded parts will be touched byit. In other words, the lead lining'being non-corrosive, the chemicalswill not affect this lining atall; and as a result the yarn may beexposed cals as much as is necessary in order ,to dye it, clean it orfor any other risk of damage from any action that might take placebetween the chemicals and certain parts of the beamconstruction.

The beam is, of course, mounted upon an operatingshaft 7 which passesthrough the heads land 2. We have shown the head 2 as being providedwith a central boss or bearing 8, one end of which is engaged bypurpose,-without to the action of the chemi- 'a nut 9 on a threadedsection 10 of the shaft '7 and a similar nut 10 are provided to enablethe shaft to engage the head 1; whereby the beam and the shaft aresecured firmly together. This 9 and threaded section I head 1 has acentralfiange or boss 11 which carries a web 12 having a central openingto accommodate the shaft 7 and a number of radial openings 13. The nut 9at this end .of the beam of course is screwed up be employed on theouter the required position in a vat, or retort, for v instance, whichisv employed in the various dyeing or other operations to which the yarnon the beam is to be subjected. The 4 openings 13 will allow the dyeingliquids, etc., to pass to or from the inside of the beam, and therotation thereof will-keep the dyestuffs and chemicals thoroughly mixedin a manner well known to those skilled in this art. The beam may beemployed for either the inward or outward treatment for the yarn and theperforations in the cylinder 4 provide for the proper circulation of thedye stufi's and chemicals therethrough; so that all parts of the mass ofyarn on the beam will be quired extent.

From the above description it will be seen that our beam combines bothcompactness and strength; and by virtue of its sectional design it canbe dismounted and taken apart with very little trouble in order torepair it or replace a broken or worn out part. It is exceedinglycompact and very cheap to make and comprises relatively few parts.

We wish to have it understood that the above description as well as thedrawings are illustrative only; and we do not care to be limited to theexact details shown and described. On the contrary we reserve toourselves the right to make such changes in the various parts as fairlyfall within the scope and spirit of our invention.

What is claimed as new is: 1. A yarn beam including a pair of heads eachhaving a recess -therein, a foundation body having its ends received insaid recesses, a--yarn bearing surface supported on said foundationbody, and means for rigidly holding said parts in assembled relation.

, .2. A yarn beamincluding a pair of heads uniformly affected to there-' body having its ends received in said grooves, a yarn bearingsurface supported on said foundation body and having perforations inregistration'with the perforations insaid body, .and tie rods passingthrough said heads and located within said foundation body to hold saidparts in assembled relation. f

'4. A yarn beam comprising a pair of heads each having an annular groovein one face, a perforated cylinder having its ends fitting into saidgrooves, ,tie rods passing through said heads and located within thecylinder for'securing the heads and cylinder together, one of said headshaving a central boss or flange carrying a perforated web, and a shaftextending through said web and the opposite head and secured to saidheads for operating said yarn beam.

5. A yarn beam including heads, arigid continuous surface foundationbody, a yarn bearing surface supported thereby, and

means assembling said heads, body and surface.

In testimony whereof, we'have signed our names to this specification inthe presence of two subscribing witnesses this 8th day, of February1915.
